*UPDATE*
I decided to just go for broke and put IBT on very high, and I got 2 soft crashes followed by a hard crash. The following is the BSOD I got. Warning: Spoiler! (Click to show)

And for a baseline test, i decided to set all my overclocking back to stock and ran IBT at vey high. I wanted to see if, well, honestly, how reliable IBT actually is. Seeing as how IBT tests CPU and memory only, I kept asking myself why would my video drivers even matter? During and IBT on very high at stock CPU settings for 5 runs, I had 9 minor screen freezes (anything that lasted longer than 2 seconds) and 1 soft crash (video cut out and came back). So if on stock settings, I can't even get a clean run of IBT, I question the usefulness of that program. I don't mean to start an argument, and I know that just cause one test succeeds doesn't necessarily mean it's right and maybe IBT is just pointing flaws in my hardware all together. But it just seems odd that if no OC settings can't pass flawless, maybe something's wrong elsewhere. Maybe it's not even IBT. I don't know.


As billbartuska mentioned never rely on mobo "auto" settings for "stock" CPU settings. The fewer settings left on auto the better off you'll be.
These are found using HWinfo64.
CPU VID (stock Vcore from AMD) is labeled Core #0 VID
CPU/NB VID (stock CPU/NB voltage from AMD) is labeled NB VID in HWinfo64. The CHV-Z usually sets the CPU/NB closer to 1.4v when left on auto.

Over-voltage causes instability the same as under-voltage and the 83xx can be very sensitive at higher clocks.

I can not offer any advice on your current settings (SS) as it does not really show me what I know is there but out of view. Please either expand HWinfo (buttons lower left corner) or reorganize to show more like my previous post (see link HWinfo volts, freq and temps)

You may not be aware but it is recommended to only run one monitoring utility at a time. Prevents possible conflicts and saves on duplication/clutter.

After you have the driver issue dealt with here are a few Bios changes that may help.
PCIe - 100
Memory freq - 1600
CPU/NB freq - 2200
Ht Link Speed - 2600
CPU Spread Spectrum - Disabled
PCIe " " " " - Disabled

CPU+NB Voltage Mode - Offset Let me know if you need more help with Offset mode. You'll need it if you plan to use C&Q (power saving features)
VID + Offset you add/enter will = Vcore in windows. This is not taking any LLC into consideration, but not ness at this point.
Make the Offset value match where you are currently at for both Vcore and CPU/NB voltage for starters.

CPU VDDA - enter what you see (2.516) get it off "auto", but watch this in windows. Asus tends to over volt.
Dram voltage - you're running 32GBs? I'd start with spec voltage and add .05 to .1v right off the bat.
NB voltage - I'd enter what I see showing - 1.113
NB HT voltage - again enter what you see - 1.211
NB 1.8v - auto is fine
SB voltage - enter what you see 1.113

CPU Power Phase Control - test at a slightly higher level than standard if all else fails
CPU Power Thermal Control - off auto, start at 130 and if needed maybe +/- two bumps and retest.
32GBs of Ram might try raising Dram Current Capability to 120 or 130%

Really need to see the loaded voltages. Vcore "seems" close to being in line judging from the result snip above.
Your test "results" 3.69729e matches my stable settings spot on for a "Standard" run but your GFlops are in the 70's while mine run low 90's even on Standard.
Tells me somethings up! System is not near balanced.

Keep us posted.

Who knows? That's why you don't use XMP - you don't know what it's doing.

Sorry for the lack of response. I got tired of some glitches in my system (sound would crackle/pop, keyboard DEL key would stop responding, start menu would sometimes freeze when clicking an item and while i could close the menu I couldn't reopen it until waiting for a few minutes for it to auto correct itself. Also, I ran 'sfc /scannow' and found 1 corrupt files each time on 2 different scans over the last few days. So I decided to scratch the whole OS install and start fresh. I spent last night before bed re-installing windows and a few programs, then since I had today off of work I spent the rest of the day getting most of my programs installed and some settings adjusted.

Then I started getting the sound popping and DEL key inoperable issues again and almost gave up by restoring a backup from my server and saying 'eff it', lol. After yet another net search for the DEL key issue, i found EVGA Precision may have been the culprit, and coincidentally may be a good enough reason to restore from said backup. So I uninstalled EVGA Precision and am now using MSI Afterburner. I'll give that a go for a few days, and hope it fixes the sound popping too. Once I polish up my windows install and make sure everything's exactly how I want it, then I'll install another copy of windows (maybe XP if I still have a copy, or perhaps 8/8.1 would be better as it's more like 10 [which is what I'm running]) onto a different SSD I have laying around and use that for my stress testing. Until then, I'm going to run on default settings in the BIOS... or maybe if I feel daring, the 4.3Ghz overclock that I had working before, with the addition of manually entered voltages for every setting that was on auto.

Either this weekend after I do my taxes, or next weekend I'll get cracking on this again.

I took Sandman's advice and set values based on his suggestions. i also went ahead and set the offset vcore, ran a small-fft stress test and took video. I tried using HWinfo64, but damn there's a lot of info in there. And also, when I launched it, it froze my Corsair Link and turned the fixed% fan RPM I set off, and on top of that it locked my CPU clock/voltage at 100% and wouldn't allow the power savings features to run. So I took a video using HWMonitor. I did a 12min small-FFT succesful run before the one I did in this video.

Vid turned out fine.

Always disable ALL power saving features in Bios when stress testing. You can re-enable after you have stability/finished testing.
Enable HPC while there too.
Don't forget to use High Performance mode in win Power Options too.

HWInfo does take a bit to reconfigure. I always do one section at a time as I feel like it lol.
HWInfo is not capable of increasing clock speed voltages etc I'm thinking more like software conflict or something left over from your earlier post yet.

Did you ever clean you setup of AI Suite? (earlier post) rolleyes.gif
These are the kinds of issues it would cause when not totally removed. It can be a real PITA, this comes from experience biggrin.gif
I vaguely remember reading Corsair Link can also raise issues but could easily be mistaken. Hopefully another Corsair user can chime in with more info here.

Again, biggest reason to reconfigure whatever utility you use is to show all the useful voltages, freq and temps. What you currently have in video shows very little of the important stuff.
Lots of good info missing.

Have another look at "my" HWInfo values starting from top down to fan speeds is enough. The mobo has a ton of sensors, better to use them so we have something to go from and save a ton of questions.


A few more changes and retest, we'll get you there biggrin.gif

I don't see why this would hurt on a known stable overclock, but ok, done. i didn't enable HPC Mode though as I don't know what it does. Some say it stop throttling, others say it's for supercomputing... eitherway, I don't see the need for it. Any fluctuations in the clock were so miniscule. Less than 100Mhz variation. Which could effect stability, as I've seen trying to push to 4.4 and 4.5, but with enough voltage, that minor flucuation shouldn't matter. Plus I wasn't approaching thermal limits either, so throttling really shouldn't need to be a worry either. Or am I wrong?

Yeah, before i even started posting here I found AI Suite was garbage. On one of my overnight blend tests I had a VCore spike to about 1.6v or something. Was funny, because at first I was thinking, wow, that's a pretty big spike. Then it hit me that 1.55v is maximum for the CPU, and I almost cried until. Then I figured out it was a false report caused by AI Suite. Also with my newest test, I closed Corsair link before launching HWInfo, just to make sure there were no mis-reading conflicts.

Without further adieu, here's the small FFT, rerun with no power savings, at my already stable 4.3Ghz (again, the whole purpose of me posting here was to get to 4.4 or 4.5Ghz, but i wanted to know how common it was to bump the CPU Voltage several increments to reach stable). Not that I don't appreciate you taking your own time to check over things as they are, I do. So, thank you.

I had a thought today, that maybe my RAM is the problem in this build. Though it's not faulty, it just may not be compatible enough. Why do I think this? Well, I can push to 4.5Ghz on <1.4v and run small FFT stress test for 15min no problem. As soon as I run Blend though, the system freezes anywhere after 5 seconds to 2:30. Or maybe it was just that the RAM timings weren't manually set and all on auto. Now that I think of that, maybe I'll try another test tonight and figure out how to set the proper timings.

If it's of any help give this a looking over http://www.overclock.net/t/1318995/official-fx-8320-fx-8350-vishera-owners-club/55800#post_24678287 as a "possible" alternative.
You'll want to read a little before, and after this post but it covers things very well.

Myself I start out with IBT AVX http://www.overclock.net/attachments/13202. Here's a couple reasons why.
In the early testing stages of a OC this usually finds instability much faster than P95. After passing 10 runs of "Very High" than time for a 20 run pass on "Maximum".
For me when it passes 20 runs on max, P95 is usually very little problem.

For testing Ram have you tried HCI MemTest http://hcidesign.com/memtest/download.html
Run one instance for each core with ram equally divided.

I'm currently running tests again on my 4.3Ghz "stable" setup. IBT standard, pass. IBT High, freeze. I always thought freezes meant low CPU voltage. Misinformation I guess. So after setting my manual RAM timings (only changed the 5 timings, as I didn't know what to do with the other 10 or so settings) and trying IBT again with another freeze, I bumped up the DRAM voltage. I think it's set to 1.51v (1.495-1.508 running IBT) and high didn't freeze. Very high currently running with ~90s passes, 84 GFlops, 3.883629e-002. On pass 4 now. Will post screenshots when done.

Needless to say, I think I solved my crash/freeze problem moving on to 4.4 and 4.5 Ghz (knock on wood). As long as I can keep the RAM stable.

Side note: my first 3-4 IBT passes run slower then the rest, is that normal?
